Anthony Pettis Fires Back at Nate Diaz for Tweet

It was assumed Nate Diaz was referring to UFC lightweight champ Anthony Pettis (pictured) when he fired off a tweet Monday wondering why his bosses were paying its athletes to pull out of fights. After all, Pettis had just bowed out of his second bout in three scheduled scraps hours earlier.

It was reported Wednesday night that Pettis tore the PCL in his knee while preparing to defend his throne against Josh Thomson at UFC on FOX 9. “Showtime” will find out next week if he’ll require surgery, which would keep him sidelined for roughly six months.

If he doesn’t need an operation, Pettis can resume training in eight weeks.

Of course, this isn’t the first time Pettis has had problems with his knees. An injured right knee forced him out of his scheduled UFC 163 fight against featherweight champ Jose Aldo.

Pettis’ exit from the December 14 card directly affected Diaz – not from a title contention standpoint, as Pettis astutely spotlighted Diaz has dropped two straight tangos – but Diaz now has to headline “The Ultimate Fighter 18 Finale” opposite Gray Maynard because that show’s original featured attraction between flyweight champ Demetrious Johnson and Joseph Benavidez was moved to replace Pettis.
